I have already tried repair clinic online and they don't carry the part.
I spoke directly with a representative from repair clinic online.
I went to E Spares.com and
1. they don't list m,y model Miele Dishwasher (my is a USA model, not European model) and
2. when I tried to see if I could buy a water valve for any of the other Miele Dishwashers that were listed, they don't have any water valves for any of the dishwashers that were listed.
O.K. i'll check back later
I sent an email to Miele.ca and this was their response.
You can purchase parts for your Miele dishwasher by calling their parts line at 1-888-529-8790. Please accept the appliance doctor's response, not mine. I just wanted to get you the number so you can get your part....
